[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This specific embodiment is a fingerprint water cup, the structural diagram of which is shown below. Figures 1-15As shown, the cup includes a cup body 1, a lid 2, a switch mechanism 5, a fingerprint recognition module, a controller 7, and a temperature display 8. The lid 2 includes a lower lid 3 located inside the cup body 1 and an upper lid 4 located above the lower lid 3. The lower lid 3 includes a lower housing 31 hinged to the upper lid 4 via a hinge shaft, a suction nozzle 32 fixedly mounted on the lower housing 31, and a rotating wheel 33 rotatably mounted between the lower housing 31 and the suction nozzle 32. A torsion spring is sleeved on the hinge shaft between the upper lid 4 and the lower housing 31. The switch mechanism 5 is located inside the lid 2. The fingerprint recognition module is fixedly mounted on the upper lid 4. The controller 7 is located inside the upper lid 4. When the owner of the cup touches the fingerprint recognition module with their finger, the controller 7 drives the switch mechanism 5 to open the upper lid 4, thereby allowing the owner of the cup to drink water. The temperature display 8 is fixedly mounted on the top of the upper lid 4 and is electrically connected to the controller 7. An upper housing 41 for accommodating the suction nozzle 32 is fixedly mounted on the inner bottom wall of the upper lid 4. A temperature probe 12 is fixedly mounted in the middle of the upper housing 41.

[0042] The controller 7 includes a circuit board fixedly installed on the inner top wall of the cover 4 and a control chip soldered on the circuit board. The fingerprint recognition module, temperature display 8 and temperature probe 12 are all connected to the circuit board through wires. The temperature probe 12 can detect the water temperature and display the temperature of the water inside the cup 1 through the temperature display 8. Therefore, with the cooperation of the temperature probe 12 and the temperature display 8, it can play the role of indicating the water temperature.

[0043] The upper cover 4 has a fixedly installed power supply 10 that is electrically connected to the controller 7. The power supply 10 is a lithium battery. The power supply 10 is connected to the circuit board through wires. The power supply 10 supplies power to the controller 7, the eccentric motor 501, the temperature probe 12 and the temperature display 8. The temperature probe 12 and the temperature display 8 are existing technologies and will not be described in detail here.

[0044] A charging interface 11 is fixedly installed on the top cover 4. A sealing plug is inserted into the charging interface 11. The sealing plug is removed when charging and inserted into the charging interface 11 when not charging to provide a sealing protection for the charging interface 11. At the same time, an internal waterproof ring and an external water sealing sheet are installed at the charging interface 11. The power supply 10 can be charged through the charging interface 11.

[0045] The switching mechanism 5 includes an eccentric motor 501 fixedly installed on the inner bottom wall of the upper cover 4, a latching piece 502 rotatably installed inside the upper cover 4, a groove opened in the inner wall of the latching piece 502, a D-shaped shaft 503 sleeved inside the latching piece 502, a transmission block fixedly installed on the D-shaped shaft 503 and adapted to the groove, a transmission piece 504 fixedly installed on the D-shaped shaft 503, and a fixing block 505 fixedly installed on the top of the lower housing 31. The fixing block 505 has a slot 5051. The eccentric motor 501 is electrically connected to the controller 7. Specifically, the eccentric motor 501 is connected to the circuit board through a wire. The transmission block is fixedly installed in the groove opened in the inner wall of the latching piece 502, so that the D-shaped shaft 503 can drive the latching piece 502 to rotate synchronously during rotation.

[0046] The snap-fit ​​piece 502 has a D-shaped shaft hole inside that mates with the D-shaped shaft 503, which makes it easy to fit the D-shaped shaft 503 into the snap-fit ​​piece 502. A waterproof silicone ring is fixedly fitted on the part of the D-shaped shaft 503 located between the snap-fit ​​piece 502 and the transmission piece 504. At the same time, a sticker is attached to the outer surface of the end of the D-shaped shaft 503 away from the transmission piece 504 to seal the shaft hole and achieve a water-sealing effect.

[0047] A first spring 506 is provided on the side of the fastening piece 502 away from the fixing block 505. One end of the first spring 506 is fixedly sleeved on the cylindrical protrusion on the side of the fastening piece 502 away from the fixing block 505, and the other end of the first spring 506 is fixedly installed on the inner wall of the upper cover 4.

[0048] When the user needs to drink the water in the cup 1, the user touches the fingerprint recognition module with their finger. The fingerprint recognition module transmits the collected fingerprint signal to the control chip. When the collected fingerprint is different from the pre-recorded fingerprint, the top cover 4 cannot be opened, and the water inside the cup 1 cannot be drunk.

[0049] When the collected fingerprint matches the pre-recorded fingerprint, the control chip controls the eccentric motor 501. When the output shaft of the eccentric motor 501 rotates, it squeezes the transmission plate 504. When the transmission plate 504 is squeezed, it drives the D-axis 503 to rotate. During the rotation of the D-axis 503, it drives the transmission block to rotate. Since the transmission block is installed in the groove of the latching piece 502, the D-axis 503 can synchronously drive the latching piece 502 to rotate during the rotation of the transmission block. During the rotation of the latching piece 502, the bottom of the latching piece 502 can be moved out of the slot 5051 of the fixing block 505. At this time, the top cover 4 is opened under the action of the torsion spring. After the top cover 4 is opened, the suction nozzle 32 is exposed, and the user can drink water.

[0050] The suction nozzle 32 is inserted into the inside of the cup body 1. The suction nozzle 32 includes a thick cylinder 3201, a thin cylinder 3202 fixedly installed in the middle of the upper surface of the thick cylinder 3201, and an annular plate 3203 fixedly installed on the top of the thick cylinder 3201. The thick cylinder 3201 is connected to the inside of the cup body 1 and the thin cylinder 3202. A locking groove 3204 is opened on the side of the annular plate 3203 away from the thin cylinder 3202. A positioning groove 3205 is opened on the annular plate 3203. A first sealing ring 321 is fixedly installed between the bottom end of the thick cylinder 3201 and the inner wall of the cup body 1. With the setting of the first sealing ring 321, the water inside the cup body 1 is sealed.

[0051] The lower housing 31 has a through hole in the middle for the thin cylinder 3202 to pass through. The lower surface of the lower housing 31 is fixedly connected with a buckling plate 3101 that cooperates with the buckling groove 3204. The lower surface of the lower housing 31 is fixedly installed with a positioning block 3102 that cooperates with the positioning groove 3205.

[0052] The rotating wheel 33 is rotatably sleeved on the coarse cylinder 3201. The bottom of the outer surface of the rotating wheel 33 is fixedly installed with an external thread, and the top of the outer surface of the rotating wheel 33 is fixedly installed with an annular rack 3301. Multiple circular protrusions 3302 are fixedly installed inside the rotating wheel 33, and the arc surface of the circular protrusions 3302 contacts the top of the coarse cylinder 3201.

[0053] The rotating wheel 33 is connected to the suction nozzle 32 as follows: the rotating wheel 33 is fitted onto the thick cylinder 3201 from the thin cylinder 3202 through the central opening structure. At this time, the arc-shaped surfaces of the multiple circular protrusions 3302 inside the rotating wheel 33 are in contact with the top of the thick cylinder 3201, and there is a small gap between the rotating wheel 33 and the annular plate 3203 at the top of the thick cylinder 3201 so that they do not contact each other. This allows the rotating wheel 33 to rotate relative to the suction nozzle 32, and the friction force when the rotating wheel 33 rotates can be reduced under the action of the circular protrusions 3302.

[0054] The connection between the lower housing 31 and the suction nozzle 32 is as follows: the fastening plate 3101 on the lower housing 31 is located inside the fastening groove 3204 opened in the annular plate 3203. With the cooperation of the fastening plate 3101 and the fastening groove 3204, the lower housing 31 provides overall support for the suction nozzle 32. The positioning block 3102 on the lower housing 31 is inserted into the positioning groove 3205 opened in the annular plate 3203. Thus, when the lower housing 31 is rotated, the lower housing 31 drives the positioning block 3102 to rotate. Since the positioning block 3102 is inserted into the positioning groove 3205, the positioning block 3102 can drive the annular plate 3203 to rotate, thereby driving the suction nozzle 32 to rotate as a whole when the lower housing 31 is rotated.

[0055] The inside of the cover 2 is also provided with a card box assembly 9. The card box assembly 9 includes a push block 901 fixedly installed on the bottom of the upper cover 4, a base plate 902 fixedly installed on the lower housing 31, a sliding block 903 slidably installed on the base plate 902, a locking block 906 fixedly installed on one side of the sliding block 903, a second spring 904 provided on the other side of the sliding block 903, and a connecting block 905 fixedly installed on the top of the sliding block 903. The bottom of the sliding block 903 is provided with a sliding groove, and a sliding rod that cooperates with the sliding groove is fixedly installed on the base plate 902. The sliding block 903 is slidably installed on the base plate 902 through the cooperation of the sliding groove and the sliding rod. The sliding rod and the sliding groove play a guiding role in the movement of the sliding block 903 and prevent the movement of the sliding block 903 from deviating.

[0056] A spring cavity is provided on the other side of the sliding block 903. One end of the second spring 904 is fixedly installed inside the spring cavity, and the other end of the second spring 904 is fixedly installed on the inner wall of the lower housing 31. Notches for sliding of the connecting block 905 are provided on both the upper cover 4 and the lower housing 31.

[0057] When the user needs to drink the water in the cup 1, the user touches the fingerprint recognition module with their finger. The fingerprint recognition module transmits the collected fingerprint signal to the control chip. When the collected fingerprint is the same as the pre-recorded fingerprint, the top cover 4 is opened. During the opening process, the push block 901 on the top cover 4 disengages from the contact block 905. At this time, the contact block 905 is no longer squeezed, and the second spring 904 is no longer squeezed. Under the reset action of the second spring 904, the sliding block 903 can be driven to move towards the annular rack 3301. During the movement, the sliding block 903 can drive the locking block 906 to move towards the annular rack 3301 until the locking block 906 enters the gap between two adjacent teeth on the annular rack 3301. Thus, when the locking block 906 rotates, it can drive the annular rack 3301 to rotate.

[0058] After the water in the cup body 1 is drunk out, by holding the lower shell 31 and rotating it clockwise, the lower shell 31 can drive the locking block 906 to rotate. The locking block 906 drives the ring rack 3301 to rotate. The ring rack 3301 drives the rotating wheel 33 to rotate. The rotating wheel 33 moves upward through the external thread and the internal thread inside the cup body 1. The rotating wheel 33 pushes the lower shell 31 upward. During the upward movement of the lower shell 31, the mouthpiece 32 moves upward through the cooperation of the latching plate 3101 and the latching groove 3204, so that the lower cover 3 can be removed from the inside of the cup body 1. At this time, water can be poured into the cup body 1.

[0059] After water is poured into the cup body 1, the lower shell 31 is held and rotated counterclockwise. During this counterclockwise rotation, the lower shell 31 drives the locking block 906 to rotate, which in turn drives the annular rack 3301. The annular rack 3301 then drives the rotating wheel 33 to rotate. The rotating wheel 33 moves downwards through its external threads and the internal threads inside the cup body 1. This downward movement presses down on the suction nozzle 32, which, through the engagement of the locking plate 3101 and the locking groove 3204, causes the lower shell 31 to move downwards, thus allowing the lower cover 3 to be fully installed inside the cup body 1. Finally, the upper cover 4 is placed on top of the lower shell. On body 31, during the closing process of upper cover 4, upper cover 4 drives push block 901 to press connecting block 905 to move away from annular rack 3301. During the movement of connecting block 905 away from annular rack 3301, it can drive sliding block 903 to move. During the movement of sliding block 903 away from annular rack 3301, it can press second spring 904. During the movement of sliding block 903 away from annular rack 3301, it can drive locking block 906 to move out from the gap between two adjacent teeth on annular rack 3301. At this time, when lower housing 31 is held and rotated, since locking block 906 is disengaged from annular rack 3301 and does not contact it, lower housing 31 is in a free-spinning state and cannot be opened.

[0060] Therefore, in this utility model, when the lid 2 is screwed onto the cup body 1, the upper lid 4 and the lower lid 3 are opened by the fingerprint lock, the lower lid 3 will not slip, and the cup body 1 and the lid 2 can be separated.

[0061] When the lid 2 is screwed onto the cup body 1, and the upper lid 4 and lower lid 3 are closed, the lower lid 3 slips and spins freely, and the lid 2 cannot be separated from the cup body 1.

[0062] The bottom of the upper cover 4 has a circular hole for the thin cylinder 3202 to pass through, and a sealing sleeve 4101 is fixedly installed on the inner bottom of the upper housing 41. When the upper cover 4 is closed on the lower housing 31, the temperature probe 12 installed on the upper housing 41 is located inside the thin cylinder 3202, and the sealing sleeve 4101 installed on the upper housing 41 contacts the top of the thin cylinder 3202, sealing the top opening of the thin cylinder 3202. Therefore, with the setting of the first sealing ring 321, the bottom of the suction nozzle 32 can be sealed, and with the setting of the sealing sleeve 4101, the top of the suction nozzle 32 can be sealed, thereby preventing water leakage. At the same time, a sealing ring can be installed between the upper cover 4 and the lower housing 1 to further improve the sealing effect.

[0063] This invention uses fingerprint recognition technology, so only users who have registered their fingerprints can open the water cup, avoiding the risk of cross-infection caused by multiple people taking the wrong water cup and ensuring drinking water hygiene.

[0064] Since only users with registered fingerprints can open the water cup, it effectively prevents others from putting foreign objects in the water cup and ensures drinking water safety;

[0065] With the temperature display 8, users can see the water temperature directly without having to rely on experience to test it, avoiding burns to the mouth or throat due to misjudgment. This is especially beneficial for children, the elderly, and people who are not sensitive to temperature, reducing the risk of burns. By checking the temperature display before drinking, users can choose the appropriate way to drink based on the actual temperature. If the temperature is too high, they can wait a while before drinking; if the temperature is suitable, they can drink directly without having to repeatedly test it.

[0066] Meanwhile, fingerprint unlocking is highly sensitive and fast, allowing users to quickly open the water cup with just a light touch of their finger, making it convenient and quick.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
